Hi all, (I'm resending this from home to avoid the DMARC->SPAM issue)
At Yahoo, load balancing is heavily used throughout our stack for both HA and load distribution, even within the OpenStack control plane itself. This involves a variety of technologies, depending on scale and other requirements. For large scale + L7 we use Apache Traffic Server, while L3DSR is the mainstay of the highest bandwidth applications and a variety of technologies are used for simple HA and lighter loads. Each of these technologies has its own special operational requirements, and although a single well-abstracted tenant-facing API to control all of them is much to be desired, there can be no such luck for operators. A major concern for us is insuring that when a tenant* has an operational issue they can communicate needs and concerns with operators quickly and effectively. This means that any operator API must @speak the same language as the user API while exposing the necessary information and controls for the underlying technology. *In this case a @tenant might represent a publicly-exposed URL with tens of millions of users or an unexposed service which could impact several such web destinations. -Ed _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
